Operation
Note 6: Set the manual absolute switch to ON position for manual operation no matter it is
before or after machining.
When a program restarting operation instead of resetting is performed after manual
operation or when manual operation is performed along the axis that has not returned to the
machining restarting position, the concerned motion is assumed to be performed as the
manual absolute switch is set to ON position regardless the manual absolute switch is at ON
or OFF position.
Note 7: In principle, the tool cannot return to the correct position in the following cases:
（
a
）
The manual absolute switch is set to OFF for manual operation.
（
b
）
When the tool is moved in the lock state of the machine or Z axis command is
camcelled.
（
c
）
Mirror image function is used.
（ d ） The coordinate system is not set at the beginning of incremental programming.
（
e
）
When manual operation is inserted during the returning of an axis.
（
f
）
When the machine lock is disabled after the program restart is commanded.
（
g
）
When program restart command is given during the execution of the cutting blocks
with ship or before the block with absolute command being executed.
（ h ） When coordinate system is established or moved after search. Nevertheless, in the
condition of (c), the P type return of the tool is available in the blocks executed with
mirror image machining is OFF and the following blocks. In this case, the state of
mirror image machining is the same as that of the interruption. in the mirror image
remains the same. No alarm is given in any case.
Note 8: When the specified block only includes M98, M99, macro program calling command
(M65, G66 and G67) or macro program statement, or block not specified is searched,
No.60 alarm will be given.
Note 9:After power on or release of emergency stop or travel limit alarm (stop immediately),
program restarting operation is commanded and G28 is detected without returning to
the reference point, P/S alarm (98) will be issued.
Note 10: After the search, P/S alarm (99) is given when a move command is executed
through MDI operations before axis motion.
Note 11: After the program restart is commanded, “RSTR” blinks at the bottom of the LCD
screen before the return of the last axis (Z).
Note 12: The block before block restarting has G28, G30, command or incremental
command. The absolute position of the 4
th
axis can be displayed at the range of 360°. In this
case, the 4
th
axis is rotate axis and the return direction of reference point is negative.
4.4.26 Comparison and Stop Function for Block
This function is used to stop machining after a command is executed to a preset sequence
number.
（ a ） Select MDI mode.
（
b
）
Press theSETTING key to display the page of “setting data 2”. Move the cursor to the
number 180 by pressing
↑ or ↓ key or pressing N 180 INPUT key.
（
c
）
Key in commands in the sequence of P
，
Sequence Number to stop
，
and INPUT .
（ d ） Select the AUTO mode. Set the machine to the preparation state for automatic operation.
（
e
）
Press Cycle Start key.
The machine stops after the data in the block whose sequence number has been preset in step
(c). Preset sequence number is cleared while the machine is stopping.
To perform another comparison stop, repeat the above procedures from (a).
Note 1: Sequence number N0 cannot be used for comparison stop.
Note 2: Preset sequence number is cleared by reset.
